We divide 356436 by 20
Let's see how many times 20 fits into 356436.

On to step 1:
The number 20 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 20

On to step 2:
35 divided by 20 is 1 with a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 20 away from 35, we end up with 15.
Include the next digit (6) from the dividend after 15, then repeat: 156 / 20

Let's proceed to step 3:
20 can be fit into 156 7 times, resulting in a remainder of 16.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Deduct 140 from 156 and we're left with 16.
Grab the next digit (4) from the dividend, add it to 16, then carry on: 164 / 20

Advancing to step 4:
The number 20 fits into 164 8 times, leaving a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 178.0
Subtract 160 from 164 to get 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 20

On to step 5:
20 can be fit into 43 2 times, resulting in a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 1782.0
Deduct 40 from 43 and we're left with 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 20

Let's proceed to step 6:
The number 20 fits into 36 1 times, leaving a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 17821.0
Deduct 20 from 36 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 7:
When dividing 160 by 20, we get 8 with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 17821.8
Subtracting 160 from 160 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 17821.8
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 17821.8
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 17821.8, and the remainder is 0.0.
